SUMMARY

Aim - evaluation of WaveLight® Oculyzer™ ii‡ (ALCON) Scheimpfug images of emetropic, myopic, hypermetric, astigmatic and excimer laser operated eyes

Material and methods
The purpose of this study is to evaluate keratometry at the anterior and posterior corneal surface, astigmatism, asphericity, cornea and anterior chamber volume and anterior chamber depths. Patients were grouped based on their refractive fgures and excimer laser surgery carried out on them.

Results
On avarage, anterior and posterior keratometry was the same in all groups (p=0.250-1.0). Mixed and combined astigmatic eyes showed differences with respect to emetropic eyes in anterior topographic astigmatizm, while in posterior topographic astigmatism this difference was more obvious in mixed astigmatic eyes. Anterior asphericity showed differences in myopic and hypermetropic excimer laser surgery carried out eyes (p=0.001 and p<0.001). Posterior asphericity was the same in all groups. Central corneal thickness was thinner in excimer laser surgery carried out myopic eyes (p<0.001). Corneal volume was different in excimer laser carried hypermetropic eyes (p=0.026). Anterior chamber volume and depths were different in myopic, hypermetropic and excimer laser carried out myopic eyes (between p=0.003 and p< 0.001).

Conclusion
Compared with emetropic eyes there were differences in topographic anterior and posterior astigmatism, central corneal thickness, cornea and anterior chamber volume and anterior chamber depths. Anterior and posterior keratometry and posterior asphericity were same in all groups.
